在交叉口的 四角位置上分别设置四个右转弯车道；
The four corners of the crossroad are respectively provided with four right-turn lanes.
针对我国现有道路交通条件下典型的信号控制交叉口，对不同车道宽度、转弯半径的右转车道的饱和车头时距进行现场测定。
Saturation time headways with different lane widths and turning radiuses were measured on the spot and abnormal data were identified and eliminated.
考虑右转车道宽度、转弯半径的影响，给出了右转车道饱和流量的回归计算模型。
A mathematical regression model on right-turning saturation flow was then established with the effect of lane width and turning radius being taken into.
右车道必须右转弯。
其中各向道路的顺右转车道直接右转弯通向右邻的逆右转车道；
The direct right-hand lane makes a direct right-hand turning to head for the right neighbouring adverse hand-right lane;
其中各向道路的顺右转车道直接右转弯通向右邻的逆右转车道；
The direct right-hand lane makes a direct right-hand turning to head for the right neighbouring adverse hand-right lane;
